GUIDES
Versions
The API's version is in the path. Today every endpoint is under /v1.
What /v1 promises
/v1 only gains fields and endpoints. A field is never renamed, retyped or removed in /v1. A change like that needs /v2, served beside /v1.
So read the fields you need and ignore any field you do not know.
The OpenAPI spec
The whole API is described in an OpenAPI 3.1 file at https://oushodh.dev/docs/openapi.json. Load it into Postman, Insomnia or a code generator.
